239
Spiegazione passo passo
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones |
| 2 | 4 | 3 | |
| - | 4 | ||
2. Subtract the numbers using long subtraction method
Because the upper digit (3) in the ones column is too small to get a positive difference, borrow 1 from the digit (4) in the next number place which becomes (3) and get (13).
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 2 | 4 | 3 | |
| - | 4 | ||
Subtract the numbers in the ones column from the top number:
13-4=9
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 2 | 4 | 3 | |
| - | 4 | ||
| 9 |
Write 3 in the tens place.
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 2 | 4 | 3 | |
| - | 4 | ||
| 3 | 9 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones |
| 3 | 13 | ||
| 2 | 4 | 3 | |
| - | 4 | ||
| 2 | 3 | 9 |
The solution is: 239
